This Engineering Undergrad Created a Pedal-Powered Recycling Machine

The machine can be built with local parts, doesn't require any fuel or electricity to run, and keeps the person doing the recycling safely away from contaminants.

Field recently won the Acer Foundation's Incredible Green Contest, and is using the prize to head back to Ghana to test out her second-generation prototype. Until electronics are better designed for repair and disassembly—and until the whole system is better designed for more local recycling in places like the United States or wherever electronics are originally in use—this is an interesting intervention.
